Oslo T-bane: CBTC project reaches important milestone

Oslo has an extensive metro network, the oldest in Scandinavia. Five lines serve 101 stations, and, in the central section, trains run every minute. Today, three different interlocking technologies are in use, some of which are already quite old. Over the next few years, operations will be converted to the communication-based train control system CBTC. At the beginning of February, four suppliers submitted initial offers for the system’s introduction and operation in the following twenty-five years. R+R supports the customer Sporveien with the evaluation of offers and the upcoming negotiations.

ETCS introduction in Finland

As part of the Europe-wide introduction of the interoperable train control system ETCS, Finland is examining the right strategy for the country. Fintraffic Rail develops pioneering digital solutions under the “Digirail” label. By the beginning of 2020, a wide range of variants had been presented, for which R + R provided rough estimates of the life cycle costs. In the meantime, Fintraffic Rail has derived an ideal solution and has examined it in depth. At the beginning of 2021, R + R developed a refined cost estimate and compared it with the costs of a fallback solution. In addition, R + R supports the assessment of cost uncertainty and the cost consequences of risks.

N1, Extension of the Zurich Northern Bypass

On September 22^nd, 2020, the third tube of the Gubrist motorway tunnel was broken through after 1,000 days of construction work and an excavation length of about 3,000m. Thus, an important milestone of the N1 Zurich Northern Bypass extension project was finally reached.

However, the work continues. Within the next two years, the construction of the roadway, the interior fittings and the installation of operating and safety equipment will follow. After completion of the third tube, three lanes will be provided for Bern-bound traffic. Commissioning and opening for regular traffic are expected to take place at the end of 2022.
